You know, I didn't think T : Point!T would work, but it does. Huh.
Anyway, the , R one works similarly, observe:

When I first saw C++ templates, I thought "what the hell is this black
magic", and had no idea how they worked. In fact, this was back before
STL, and I recall it was a set of templates

Your confusion arises in your understanding of meta programming
and templates. Templates are compile time expressions that use

This sounds like another 'no.' :)

In Michael Parker's book, "Learning D," (Packt, 2015) on page
